Description

Die vorliegende Erfindung betrifft eine teleskopierbare Hubsäule eines Möbelteils, insbesondere eines höhenverstellbaren Möbelbeins gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a telescopic lifting column of a furniture part, in particular a height-adjustable furniture leg according to the preamble of claim 1.

Gattungsgemäße Hubsäulen für solche teleskopierbaren Möbelteile, beispielsweise in Gestalt höhenverstellbarer Möbelbeine wie Tischbeine und dergleichen, sind in zahlreichen Ausführungsvarianten aus dem Stand der Technik bekannt. Sie weisen üblicherweise eine Antriebseinheit auf, die in der Regel außerhalb des Möbelbeins an dem Möbel befestigt ist und die zwei oder mehr aneinander gekoppelte Spindeln antreibt, welche ihrerseits über einen Mitnehmer an jeweils ein Säulenprofil angekoppelt sind. Die Säulenprofile sind dabei oft zylinderförmig oder als Hohlsäulen mit quadratischem Querschnitt ausgestaltet, wobei der Querschnitt bzw. Durchmesser der äußeren Säule geringfügig größer ist als der Querschnitt oder Durchmesser einer inneren Säule.Generic lifting columns for such telescopic furniture parts, for example in the form of height-adjustable furniture legs such as table legs and the like, are known in numerous variants of the prior art. They usually have a drive unit, which is usually attached to the furniture outside of the furniture leg and the two or more coupled spindles drives, which in turn are coupled via a driver to a respective pillar profile. The column profiles are often cylindrical or configured as hollow columns with a square cross section, wherein the cross section or diameter of the outer column is slightly larger than the cross section or diameter of an inner column.

Mit der Veränderung des Querschnitts dieser Säulenprofile geht dabei stets ein Austausch aller Komponenten der Antriebseinheit einher, da diese entsprechend dem sie umgebenden Säulenprofil geformt und angepasst sind.With the change in the cross section of these column profiles is always accompanied by an exchange of all components of the drive unit, since they are shaped and adapted according to the surrounding pillar profile.

Aus der DE 202 14 566 U1 ist eine teleskopierbare Hubsäule bekannt, bei der zur Erleichterung der Montage eine zweiteilige Spindelmutter auf eine Spindel aufgesetzt ist. An dieser Spindelmutter ist im äußeren Umfangsbereich eine Ringnut angeformt, in der das sie umgebende Säulenprofil festgesetzt ist.From the DE 202 14 566 U1 a telescopic lifting column is known in which a two-part spindle nut is placed on a spindle to facilitate assembly. At this spindle nut an annular groove is formed in the outer peripheral region in which the surrounding pillar profile is fixed.

Aufgabe der vorliegenden Erfindung ist es, eine teleskopierbare Hubsäule eines Möbelteils bereitzustellen, bei der Säulenprofile unterschiedlicher Skalierungen und unterschiedlich gestalteter Querschnitte einsetzbar ist.Object of the present invention is to provide a telescopic lifting column of a furniture part, in the column profiles of different scales and differently shaped cross sections can be used.

Diese Aufgabe wird durch eine teleskopierbare Hubsäule eines Möbelteils gemäß den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a telescopic lifting column of a furniture part according to the features of claim 1.

Die teleskopierbare Hubsäule weist neben der Antriebseinheit wenigstens zwei Säulenprofile auf, die ineinander in Längsrichtung der Säulenprofile verfahrbar sind. Auf wenigstens einer von der Antriebseinheit mittelbar antreibbaren Spindel, ist eine gegenüber einem der Säulenprofile drehgesicherte Spindelmutter durch Rotation in Längsrichtung der wenigstens einen Spindel verfahrbar, wobei die drehgesicherte Spindelmutter mittelbar mit einem der Säulenprofile in Wirkverbindung steht. Die wenigstens eine Spindelmutter ist dabei als mehrteilige Spindelmutter ausgebildet und weist eine Außenkontur zur drehgesicherten mittelbaren Wirkverbindung mit einem der Säulenprofile auf. Die mittelbare Wirkverbindung zwischen Spindelmutter und Säulenprofil wird dabei durch einen mehrteilig, insbesondere zweiteilig ausgebildet Mitnehmer gebildet.The telescopic lifting column has, in addition to the drive unit, at least two column profiles which are movable into one another in the longitudinal direction of the column profiles. On at least one spindle indirectly driven by the drive unit, a spindle nut secured against rotation relative to one of the column profiles can be moved by rotation in the longitudinal direction of the at least one spindle, wherein the rotationally secured spindle nut is in operative connection with one of the column profiles. The at least one spindle nut is designed as a multipart spindle nut and has an outer contour for the rotationally secured indirect operative connection with one of the pillar profiles. The indirect operative connection between the spindle nut and the pillar profile is formed by a multipart, in particular two-part driver.

Die Mehrteiligkeit der Spindelmuttern hat insbesondere den Vorteil einer einfachen Montage, da die Spindelmuttern einfach an einer beliebigen Position der Spindel aufgesetzt werden können und nicht vorab auf die Spindeln aufgedreht werden müssen. Dies erweist sich insbesondere dann als Vorteil, wenn die zur Übertragung der Rotationsbewegung zwischen den Spindeln an den Spindeln angebrachten Spindeladapter im Rahmen einer Vormontage angeschweißt werden.The multi-part of the spindle nuts in particular has the advantage of ease of assembly, since the spindle nuts can be easily placed at any position of the spindle and does not need to be turned on the spindles in advance. This proves to be an advantage in particular when the spindle adapters for transmitting the rotational movement between the spindles to the spindles are welded in the course of a pre-assembly.

Die Mehrteiligkeit der Mitnehmer und insbesondere die Trennung von Spindelmuttern und Mitnehmern ist von großem Vorteil, da zur Änderung des Querschnitts des Säulenprofils die Antriebsvorrichtung selbst unverändert beibehalten werden kann. Angepasst werden müssen lediglich die auf die Spindelmuttern aufgesetzten Mitnehmer. Dies gewährleistet eine relative Designfreiheit und Skalierbarkeit der äußeren Säulenprofile.The multi-part of the driver and in particular the separation of spindle nuts and drivers is of great advantage, since the drive device itself can be maintained unchanged to change the cross section of the column profile. Only the drivers mounted on the spindle nuts need to be adjusted. This ensures relative design freedom and scalability of the outer pillar profiles.

Die Trennung von Spindelmutter und Mitnehmer hat des Weiteren den großen Vorteil, dass für die einzelnen Bauteile entsprechende vorteilhafte Werkstoffe verwendet werden können. So werden für die Spindelmuttern als Werkstoffe bevorzugt Gleitlagerwerkstoffe verwendet, für die Mitnehmer hingegen gut verklebbare Werkstoffe.The separation of the spindle nut and driver also has the great advantage that corresponding advantageous materials can be used for the individual components. For example, plain bearing materials are the preferred materials for the spindle nuts, while materials that can be easily bonded can be used for the drivers.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Die Spindelmutterteile der mehrteiligen Spindelmutter sind gemäß einer Ausführungsvariante formschlüssig und / oder kraftschlüssig, insbesondere mit Rastverbindungen zusammenfügbar, um diese sicher auf dem Gewinde der jeweiligen Spindel zu halten.The Spindelmutterteile the multi-part spindle nut are according to a variant form-fitting and / or non-positively, in particular with latching connections joined together to keep them safely on the thread of the respective spindle.

Auch die Mitnehmerteile des mehrteiligen Mitnehmers sind bevorzugt formschlüssig und / oder kraftschlüssig, insbesondere mit Rastverbindungen zusammenfügbar.The driver parts of the multipart driver are preferably positive and / or non-positive, in particular with latching connections joined together.

Gemäß einer weiteren bevorzugten Ausführungsvariante ist jedes Spindelmutterteil der mehrteiligen Spindelmutter gleich. Damit ist eine kostengünstige Herstellung und auch Lagerhaltung dieser Bauteile ermöglicht.According to a further preferred embodiment, each spindle nut part of the multipart spindle nut is the same. For a cost-effective production and storage of these components is possible.

Bei einer symmetrischen Außenform des Säulenprofils ist bevorzugt jedes Mitnehmerteil des mehrteiligen Mitnehmers baugleich. Ist die Außenform des Säulenprofils hingegen unsymmetrisch, sind die Mitnehmerteile des mehrteiligen Mitnehmers bevorzugt ungleich.In a symmetrical outer shape of the pillar profile of each driver part of the multi-part carrier is preferably identical. However, if the outer shape of the pillar profile is asymmetrical, the driver parts of the multipart driver are preferably unequal.

Gemäß einer weiteren bevorzugten Ausführungsvariante der Erfindung sind in mindestens einem der Mitnehmer an einer parallel zur Innenfläche der Säulenprofile, die die Spindeln und das Antriebsrohr umgeben, verlaufenden Außenfläche Gleitelemente befestigbar, mit denen eine exakte Führung der Säulenprofile während des Teleskopierprozesses gewährleistet ist.According to a further preferred embodiment of the invention sliding elements are fastened in at least one of the drivers on a parallel to the inner surface of the column profiles, which surround the spindles and the drive tube, extending outer surface, with which an exact guidance of the column profiles is ensured during the Teleskopierprozesses.

Gemäß der Erfindung sind die mehrteiligen Spindelmuttern relativ zu den mehrteiligen Mitnehmern im an der jeweiligen Spindel aufgesetzten Zustand axial um wenigstens 30° Grad, vorzugsweise um 90 Grad, versetzt zueinander angeordnet. Dadurch überlappen sich die Schnittbereiche der geteilten Spindelmuttern und Mitnehmern, was insbesondere den Sitz der Spindelmuttern auf dem Gewinde der jeweiligen Spindel unterstützt und eine sichere Einbettung der mehrteiligen Spindelmuttern in den mehrteiligen Mitnehmern gewährleistet.According to the invention, the multi-piece spindle nuts are offset relative to the multi-part carriers in the state attached to the respective spindle axially by at least 30 degrees, preferably by 90 degrees arranged to each other. As a result, overlap the sectional areas of the split spindle nuts and drivers, which in particular supports the fit of the spindle nuts on the thread of the respective spindle and ensures a secure embedding of the multi-part spindle nuts in the multi-part carriers.

Gemäß einer Ausführungsvariante der Erfindung ist die erste Spindel als Hohlspindel und die zweite Spindel als Vollspindel ausgebildet, so dass die Hohlspindel in dem Antriebsrohr und die Vollspindel in der Hohlspindel verfahrbar ist.According to one embodiment of the invention, the first spindle is designed as a hollow spindle and the second spindle as a full spindle, so that the hollow spindle in the drive tube and the full spindle in the hollow spindle can be moved.

Die Spindelmuttern 28, 29 selbst sind dabei als mehrteilige Spindelmuttern, insbesondere als zweiteilige Spindelmuttern 28, 29 ausgebildet, wobei jede der Spindelmuttern 28, 29 in einer Schnittebene parallel zur Längserstreckung der Spindeln 26, 27 und entlang eines Durchmessers des Querschnitts der Spindeln in zwei Spindelmutterteile 28a, 28b bzw. 29a, 29b aufgeteilt sind. In gleicher Weise sind auch die Mitnehmer 7, 8 in Mitnehmerteile 7a, 7b, 8a, 8b, vorzugsweise in zwei Hälften aufgeteilt. Die Spindelmuttern 28, 29 können so in einfacher Weise an der jeweiligen Spindel 26, 27 aufgesetzt werden und durch anschließendes Aufsetzen der Mitnehmerteile 7a, 7b bzw. 8a, 8b auf die Spindelmutterteile 28a, 28b bzw. 29a, 29b und Einsetzen der Mitnehmer 7, 8 in das Hohlprofil eines der Säulenprofile 5, 6 sind die Säulenprofile 5, 6 durch Rotation der Spindeln 26, 27 in eine gewünschte Position verfahrbar.A variant of an inventive drive device of a telescopic furniture part is in Fig. 1 shown as an exploded view in the form of a height-adjustable furniture leg, wherein the drive device of the furniture leg substantially from a drive unit 37, one of the drive unit 37 driven first spindle 26 (shown in FIG Fig. 4 ), on which a first rotationally secured spindle nut 28 can be moved by rotation in the longitudinal direction of the first spindle 26 and a second spindle 27 (shown in FIG. 1) that can be moved to the first spindle 26 in the longitudinal direction of the first spindle 26 Fig. 6 ), on which a second rotationally secured spindle nut 29 in the longitudinal direction of the second spindle 27 is movable. The spindle nuts 28, 29 themselves are designed as multi-part spindle nuts, in particular as two-part spindle nuts 28, 29, wherein each of the spindle nuts 28, 29 in a sectional plane parallel to the longitudinal extent of the spindles 26, 27 and along a diameter of the cross section of the spindles in two Spindelmutterteile 28a, 28b and 29a, 29b are divided. In the same way, the drivers 7, 8 in driver parts 7a, 7b, 8a, 8b, preferably divided into two halves. The spindle nuts 28, 29 can be placed in a simple manner to the respective spindle 26, 27 and by subsequent placement of the driver parts 7a, 7b and 8a, 8b on the Spindelmutterteile 28a, 28b and 29a, 29b and insertion of the driver 7, 8 in the hollow profile of one of the column profiles 5, 6, the column profiles 5, 6 can be moved by rotation of the spindles 26, 27 in a desired position.

Wie in Fig. 1 des Weiteren zu erkennen ist, sind die erste Spindel 26 und die zweite Spindel 27 im eingefahrenen Zustand der Hubsäule von einem Antriebsrohr 24 umgeben, das über einen ersten Spindeladapter (nicht gezeigt), der in ein Hohlprofil 57, gezeigt in den Fig. 3 und 4, einsetzbar ist und von der Antriebseinheit 37 angetrieben wird und in dem die erste Spindel 26 in Längsrichtung des Antriebsrohres 24 verfahrbar ist, wie es beispielsweise in Fig. 4 gezeigt ist.As in Fig. 1 can be seen further, the first spindle 26 and the second spindle 27 are surrounded in the retracted state of the lifting column of a drive tube 24, which via a first spindle adapter (not shown), which in a hollow section 57, shown in the 3 and 4 , Is used and is driven by the drive unit 37 and in which the first spindle 26 in the longitudinal direction of the drive tube 24 is movable, as for example in Fig. 4 is shown.

Die Fig. 2 zeigt die Hubsäule 1 im zusammengesetzten und eingefahrenen Zustand in Gestalt eines Möbelbeins, insbesondere eines Tischbeins, mit drei ineinander gesteckten Säulenprofilen 4, 5, 6, welche die darin untergebrachte Antriebseinheit 37 von außen verdecken.The Fig. 2 shows the lifting column 1 in the assembled and retracted state in the form of a furniture leg, in particular a table leg, with three nested column profiles 4, 5, 6, which hide the drive unit 37 accommodated therein from the outside.

In dem hier ersten Säulenprofil 6 ist eine Anbindungsplatte 12 eingelassen, mit der die Hubsäule 1 beispielsweise an einer hier nicht dargestellten Unterseite einer Tischplatte befestigt werden kann.In the here first pillar profile 6, a connection plate 12 is inserted, with which the lifting column 1, for example, on a bottom, not shown here a table top can be attached.

Die Anbindungsplatte 12 wird vorzugsweise in einer dazu angeformten Tasche 44 am oberen Ende des innersten Säulenprofils 6 eingelassen und dort vorzugsweise verschraubt. Die Antriebseinheit 37 ist an dieser Anbindungsplatte 12 festgelegt. An dem der Anbindungsplatte 12 abgewandten Ende der Antriebseinheit 37 ist der erste Spindeladapter (nicht dargestellt), der mit der (hier nicht gezeigten) Abtriebswelle des Getriebes der Antriebseinheit 37 im Wirkverbindung steht, befestigt und greift im montierten Zustand in das Hohlprofil 57 des Antriebsrohrs 24 ein und versetzt dieses beim Betreiben des Motors 11 in Rotation.The connection plate 12 is preferably embedded in a pocket 44 formed thereon at the upper end of the innermost column profile 6 and preferably screwed there. The drive unit 37 is fixed to this connection plate 12. At the end of the drive unit 37 facing away from the connection plate 12, the first spindle adapter (not shown), which is operatively connected to the output shaft of the transmission of the drive unit 37, is fastened and engages in the hollow profile 57 of the drive tube 24 in the mounted state and puts this in operation of the motor 11 in rotation.

Wie insbesondere in Fig. 4 gezeigt, ist in dem Antriebsrohr 24 in Längsrichtung des Antriebsrohrs 24 eine erste Spindel 26 verfahrbar, die über eine erste Spindelmutter 28 einen ersten Mitnehmer 7 antreibt, der mit dem ersten Säulenprofil 6 in Wirkverbindung steht. Dabei wird die erste Spindel 26 durch das Antriebsrohr 24 in Rotation versetzt, bevorzugt über einen an einem oberen Ende der ersten Spindel 26 befestigten zweiten Spindeladapter 25, der in einen Innenkontur des Antriebsrohrs 24 eingreift, wobei durch die Rotation der ersten Spindel 26 in der Spindelmutter 28 sich die Spindelmutter 28 in Längsrichtung der ersten Spindel 26 nach oben oder unten bewegt, dabei den ersten Mitnehmer 7 mitnimmt und dadurch das erste Säulenprofil 6 nach oben oder unten schiebt.As in particular in Fig. 4 shown, in the drive tube 24 in the longitudinal direction of the drive tube 24, a first spindle 26 can be moved, which drives a first driver 7 via a first spindle nut 28, which is in operative connection with the first column profile 6. In this case, the first spindle 26 is rotated by the drive tube 24 in rotation, preferably via a second spindle adapter 25 attached to an upper end of the first spindle 26, which engages in an inner contour of the drive tube 24, wherein by the rotation of the first spindle 26 in the spindle nut 28, the spindle nut 28 moves in the longitudinal direction of the first spindle 26 up or down, thereby entraining the first driver 7 and thereby pushes the first pillar profile 6 up or down.

Diese erste Spindel 26 ist dabei vorzugsweise als Hohlspindel ausgebildet, in der eine vorzugsweise als Vollspindel ausgebildete zweite Spindel 27 in Längsrichtung Z der Spindel verfahrbar ist. Die zweite Spindel 27 treibt dabei über eine zweite Spindelmutter 29 einen zweiten Mitnehmer 8 an, welcher mit einem zweiten Säulenprofil 5 in Wirkverbindung steht, in dem das erste Säulenprofil 6 in Längsrichtung des Antriebsrohrs 24 oder des Säulenprofils 5, 6 verfahrbar ist.This first spindle 26 is preferably formed as a hollow spindle, in which a preferably designed as a full spindle second spindle 27 in the longitudinal direction Z of the spindle is movable. The second spindle 27 drives via a second spindle nut 29, a second driver 8, which is in operative connection with a second column profile 5, in which the first column profile 6 in the longitudinal direction of the drive tube 24 or the column profile 5, 6 is movable.

Die Hubsäule 1 weist ein drittes Säulenprofil 4 auf, welches über einen an einem Ende der zweiten Spindel 27 befestigten dritten Spindeladapter 35 die zweite Spindel 27 umgibt und in dem das zweite Säulenprofil 5 in Längsrichtung des Antriebsrohrs 24 verfahrbar ist. In der Einfahrstellung der Hubsäule 1 ist somit im Wesentlichen nur das dritte Säulenprofil 4 zu sehen, in das die weiteren Säulenprofile 5 und 6 einfahrbar sind und nur am oberen, der Anbindungsplatte 12 nahen Ende geringfügig hervorstehen.The lifting column 1 has a third column profile 4, which surrounds the second spindle 27 via a third spindle adapter 35 fastened to one end of the second spindle 27 and in which the second column profile 5 can be moved in the longitudinal direction of the drive tube 24. In the retracted position of the lifting column 1 is thus substantially only the third pillar profile 4 can be seen, in which the other pillar profiles 5 and 6 are retractable and only slightly protrude at the top, the connection plate 12 near end.

Der der Anbindungsplatte 12 nahe obere Abschluss des äußeren Säulenprofils 4 und des mittleren Säulenprofils 5 wird dabei vorzugsweise durch in Fig. 1 gezeigte Rahmen 2 und 3 abgedeckt. Die beiden Rahmen 2, 3 werden dabei von oben in die Säulenprofile 4 und 5 eingesteckt und dienen neben der Abdeckung des oberen Rands der Säulenprofile 4 und 5 auch der Führung des jeweils im äußeren Säulenprofil 4 bzw. 5 verfahrbar angeordneten inneren Säulenprofils 5 bzw. 6.The connection plate 12 near upper end of the outer pillar profile 4 and the central pillar profile 5 is preferably by in Fig. 1 shown frames 2 and 3 covered. The two frames 2, 3 are inserted from above into the pillar profiles 4 and 5 and serve in addition to the cover of the upper edge of the pillar profiles 4 and 5 and the leadership of each in the outer pillar profile 4 and 5 movably arranged inner pillar profile 5 and 6 respectively ,

Die Länge des Antriebsrohrs 24 ist so bemessen, dass die Antriebseinheit 37 in das erste Säulenprofil 6 integriert werden kann.The length of the drive tube 24 is dimensioned such that the drive unit 37 can be integrated into the first column profile 6.

Damit ist das Antriebsrohr 24 sowie die erste und zweite Spindel 26, 27 mit gleicher Drehzahl in gleicher Drehrichtung rotierend von der Antriebseinheit 37 antreibbar.Thus, the drive tube 24 and the first and second spindle 26, 27 with the same rotational speed in the same direction of rotation of the drive unit 37 can be driven.

Die Spindelmutterteile 28a, 28b, 29a, 29b sind bevorzugt formschlüssig und / oder kraftschlüssig zusammenfügbar. Wie insbesondere in den Fig. 5 und 7 gezeigt, weisen die Spindelmutterteile 28a, 28b, 29a, 29b seitlich vorzugsweise Rastnasen 50, 58 bzw. Rastbügel 51, 59 auf, die die beiden Hälften 28a, 28b bzw. 29a, 29b im an der Spindel 26, 27 aufgesetzten Zustand zu einer die Spindel 26, 27 umfassenden Spindelmutter 28, 29 zusammenhalten.The Spindelmutterteile 28a, 28b, 29a, 29b are preferably form-fitting and / or non-positively assembled. As in particular in the Fig. 5 and 7 shown, the Spindelmutterteile 28a, 28b, 29a, 29b laterally preferably locking lugs 50, 58 and latching bracket 51, 59, the two halves 28a, 28b and 29a, 29b in the attached to the spindle 26, 27 state to a the Spindle 26, 27 comprehensive spindle nut 28, 29 hold together.

Ebenso sind die Mitnehmerteile 7a, 7b, 8a, 8b des mehrteiligen Mitnehmers 7, 8 bevorzugt formschlüssig und / oder kraftschlüssig, insbesondere mit Rastverbindungen (nicht dargestellt) zusammenfügbar.Likewise, the driver parts 7a, 7b, 8a, 8b of the multi-part driver 7, 8 are preferably connected in a form-fitting and / or non-positive manner, in particular with latching connections (not shown).

Des Weiteren erstreckt sich ausgehend von den in den Gewinden der Spindelmutterteile 28a, 28b, 29a, 29b radial nach außen eine Außenkontur 43, 48, die in entsprechend geformte Ausnehmungen 42, 49 der Mitnehmerteile 7a, 7b, 8a, 8b eingreifen. Diese Außenkonturen 43, 48 sowie die Ausnehmungen 42, 49 bilden dabei einen Formschluss, so dass eine Drehbewegung der Spindel 26, 27 in der Spindelmutter 28, 29 eine Längsverschiebung in Richtung der Längserstreckung Z der Spindel 26, 27 bewirkt, damit die Mitnehmer 7, 8 entlang der jeweiligen Spindel 26, 27 nach oben oder unten geschoben werden und dementsprechend die sich auf dem Mitnehmer 7, 8 abstützenden Säulenprofile 5, 6 in Längsrichtung Z verschoben werden.Furthermore, starting from the threads in the spindle nut parts 28a, 28b, 29a, 29b extending radially outwardly an outer contour 43, 48 which engage in correspondingly shaped recesses 42, 49 of the driver parts 7a, 7b, 8a, 8b. These outer contours 43, 48 and the recesses 42, 49 form a positive connection, so that a rotational movement of the spindle 26, 27 in the spindle nut 28, 29 causes a longitudinal displacement in the direction of the longitudinal extent Z of the spindle 26, 27, so that the driver 7, 8 are pushed along the respective spindle 26, 27 upwards or downwards and accordingly the column profiles 5, 6 supported on the driver 7, 8 are displaced in the longitudinal direction Z.

Durch die Trennung der Spindelmuttern 28, 29 von den Mitnehmern 7, 8 ist es in einfacher Weise möglich, die Mitnehmer 7, 8 an einen geänderten Querschnitt der Säulenprofile 4, 5, 6 anzupassen. Insbesondere muss die Antriebsvorrichtung selbst nicht verändert werden, sondern lediglich die Gestalt der Mitnehmer 7, 8 sowie des am unteren Ende des äußersten Säulenprofils 4 eingesetzten Fußadapters 9, in dem zentral die als Vollspindel ausgebildete zweite Spindel 27 in einem Lagerfuß 52 gelagert ist sowie die am oberen Ende der Hubsäule 1 angebrachte Anbindungsplatte 12 und ggf. ein Momentaufnehmer der Antriebseinheit 37.By separating the spindle nuts 28, 29 of the drivers 7, 8, it is possible in a simple manner, the driver 7, 8 adapt to a modified cross-section of the column profiles 4, 5, 6. In particular, the drive device itself need not be changed, but only the shape of the driver 7, 8 and the foot adapter used at the bottom of the outermost column profile 4 9, in which centrally formed as a full spindle second spindle 27 is mounted in a bearing 52 and the on attached to the upper end of the lifting column 1 connection plate 12 and possibly a snapshot of the drive unit 37th

Die mehrteiligen Spindelmuttern 28, 29 sind relativ zu den mehrteiligen Mitnehmern 7, 8 im an der jeweiligen Spindel 26, 27 aufgesetzten Zustand axial um wenigstens 30 Grad versetzt zueinander angeordnet. Bei der in den Fig. 6 und 7 gezeigten Ausführungsvariante sind die Spindelmuttern 28, 29 um 90 Grad versetzt zu den mehrteiligen Mitnehmern 7, 8 angeordnet.The multi-part spindle nuts 28, 29 are arranged relative to the multi-part carriers 7, 8 in the attached to the respective spindle 26, 27 state axially offset by at least 30 degrees to each other. In the in the 6 and 7 embodiment shown, the spindle nuts 28, 29 offset by 90 degrees to the multi-part dogs 7, 8 are arranged.

In den Fig. 10a und 10b sind beispielhaft zwei unterschiedliche Ausgestaltungen solcher Mitnehmerteile 7a, 7b, 8a, 8b gezeigt. So sind die zu einem Mitnehmer 7, 8 zusammensetzbaren Mitnehmerteile 7a, 7b, 8a, 8b bei einer symmetrischen Außenform des Säulenprofile 4, 5, 6 baugleich, wie es in Fig. 10b anhand eines rechteckförmig gestalteten einen Mitnehmerteils 7a, 7b, 8a, 8b gezeigt ist.In the 10a and 10b For example, two different embodiments of such driver parts 7a, 7b, 8a, 8b are shown. Thus, the driver parts 7a, 7b, 8a, 8b which can be assembled to form a driver 7, 8 are of identical design in the case of a symmetrical outer shape of the pillar profiles 4, 5, 6, as is shown in FIG Fig. 10b with reference to a rectangular shaped one driver part 7a, 7b, 8a, 8b is shown.

Bei einer unsymmetrischen Außenform der Säulenprofile 4, 5, 6 hingegen (gezeigt in Fig. 10a) ist beispielsweise eines der Mitnehmerteile 7a, 7b, 8a, 8b trapezförmig ausgestaltet, während das andere der beiden zu einem Mitnehmer 7, 8 zusammensetzbaren Mitnehmerteile 7a, 7b, 8a, 8b beispielsweise wiederum rechteckig geformt ist, so dass die beiden zu einem Mitnehmer 7, 8 zusammensetzbaren Mitnehmerteile 7a, 7b, 8a, 8b ungleich sind.In contrast, in the case of an asymmetrical outer shape of the pillar profiles 4, 5, 6 (shown in FIG Fig. 10a ), for example, one of the driver parts 7a, 7b, 8a, 8b designed trapezoidal, while the other of the two can be assembled to a driver 7, 8 driver parts 7a, 7b, 8a, 8b, for example, again rectangular, so that the two to a driver , 8 composite driver parts 7a, 7b, 8a, 8b are unequal.

Gut zu erkennen in diesen Figuren sind auch die Stützkanten 55, auf denen die Stirnkanten der Säulenprofile 5, 6 aufliegen und beispielsweise durch Bohrungen 54 mittels Schrauben in den Mitnehmerteilen angeschraubt sind.Good to see in these figures are also the support edges 55, on which rest the end edges of the column profiles 5, 6 and are screwed for example by holes 54 by means of screws in the driver parts.

Die Trennung von Spindelmutter 28, 29 und Mitnehmer 7, 8 hat des Weiteren den großen Vorteil, dass für die einzelnen Bauteile entsprechend optimierte Werkstoffe verwendet werden können. So werden für die Spindelmutter als Material bevorzugt Gleitlagerwerkstoffe verwendet, beispielsweise POM (Polyoxymethylen) oder PA (Polyamid), für die Mitnehmer hingegen relativ gut verklebbare Werkstoffe, insbesondere ABS (Acrylnitril-Butadien-Styrol) oder PE (Polyethylen).The separation of spindle nut 28, 29 and driver 7, 8 also has the great advantage that correspondingly optimized materials can be used for the individual components. For example, plain bearing materials are preferably used as material for the spindle nut, for example POM (polyoxymethylene) or PA (polyamide), but relatively well bondable materials for the drivers, in particular ABS (acrylonitrile-butadiene-styrene) or PE (polyethylene).

Um die Längsverschiebung der Säulenprofile 4, 5, 6 ineinander zu erleichtern, sind bevorzugt in den Eckbereichen der Rahmen 2, 3 Aussparungen 45 für den Einsatz von Gleitelementen 36 vorgesehen, so dass die Säulenprofile 4, 5, 6 einerseits an ihrem fußseitigem Ende durch die Mitnehmer 7, 8 und den Fußadapter 9 geführt sind und an ihrem kopfseitigem Ende durch die Rahmen 2, 3 und den darin angebrachten Gleitelementen 36 in ihrer zentrierten Position geführt werden.In order to facilitate the longitudinal displacement of the column profiles 4, 5, 6 into each other, recesses 45 are preferably provided in the corner regions of the frame 2, 3 for the use of sliding elements 36, so that the column profiles 4, 5, 6 on the one hand at their fußseitigem end by the Carrier 7, 8 and the foot adapter 9 are guided and guided at its head end through the frame 2, 3 and the sliding elements 36 mounted therein in its centered position.
